Description

Vasopressin, β-Mercapto Beta,β-Cyclopentamethylenepropionic Acid(1)-o-Ethyl-Tyr(2)-Val(4)-Cit(8)- is a synthetic, modified peptide analog of the neurohypophysial hormone vasopressin, designed for enhanced stability and specific receptor interaction. This compound is of significant value in advanced pharmaceutical research and development, particularly for studying vasopressin receptor subtypes and developing novel therapeutic agents. It is primarily needed by biotechnology firms, pharmaceutical R&D laboratories, and academic institutions focused on endocrinology, cardiovascular research, and central nervous system disorders.

Application

• Pharmaceutical Research & Development: As a key reference standard and active pharmaceutical ingredient (API) intermediate in the development of novel vasopressin receptor agonists or antagonists.
• Biochemical Research: For studying the structure-activity relationships (SAR) of vasopressin and its interaction with V1a, V1b, and V2 receptors in vitro.
• Drug Discovery Programs: Utilized in high-throughput screening assays to identify and characterize new drug candidates targeting vasopressin pathways.
• Academic Studies: Investigation into the physiological roles of vasopressin in blood pressure regulation, renal water reabsorption, and social behavior.
• Peptide Chemistry Development: Serves as a complex model compound for developing and optimizing novel peptide synthesis, purification, and stabilization techniques.
